A crate of mass m1 = 12.4 kg is pulled by a
massless rope up a 36.9° ramp. The rope passes over an ideal pulley
and is attached to a hanging crate of mass m2 =
16.3 kg. The crates move 1.70 m, starting from rest. If the
frictional force on the sliding crate has magnitude 21.7 N and the
tension in the rope is 121.5 N, find the total work done on the
sliding crate.
The total work done...
A crate of mass m1 = 12.4 kg is pulled by a massless rope up a 36.9° ramp. The rope passes over an ideal pulley and is attached to a hanging crate of mass m2 = 16.3 kg. The crates move 1.40 m, starting from rest. If the frictional force on the sliding crate has magnitude 22.6 N and the tension in the rope is 121.5 N, find the total work done on the sliding crate.
A crate of mass m1 = 11.4 kg is pulled by a massless rope up a 36.9° ramp. The rope passes over an ideal pulley and is attached to a hanging crate of mass m2 = 16.3 kg. The crates move 2.70 m, starting from rest. Find the final speed of the sliding crate if the incline is frictionless.
An apple at 30°C with average mass of 0.2 kg and average specific heat of 3.65 kJ/kg °C is in contact with a 0.1 kg cold iron at 10 °C. Determine the final temperature of the apple and the heat transfer between apple and iron. Use appendix to find the specific heat for iron. Neglect change of KE and PE of the system.

Explanation
Since energy is conserved and nonconservative forces do no work,
mechanical energy is conserved. Let the y-axis point
straight upward....

Problem 4.39
Two crates, one with mass 4.00 kg and the other with mass 6.00 kg, sit on the frictionless surface of a frozen pond, connected by a light rope (Figure 1). A woman wearing golf shoes (so she can get traction on the ice) pulls horizontally on the 6.00 kg crate with a force F that gives the crate an acceleration of 290 m/s 6.00 kg よ 00 kg T he woman is pulling two c rope that connects...
A crate with a mass of 161.5 kg is suspended from the end of a
uniform boom with a mass of 71.3 kg. The upper end of the boom is
supported by a cable attached to the wall and the lower end by a
pivot (marked X) on the same wall. Calculate the tension in the
cable.
